Re: “Am I right in thinking that scientific experiments have demonstrated that time passes at a slightly different rate outside the earths gravity well?”I don't think so, no.

Velocity affects time (it slows it.) And a gravity well affects time (by bending space-time.) But merely being IN a gravity well? I think time would move at the same rate for those who are in the well as for those who are outside of it. If you're on the Earth and someone is well away from Earth and not in a gravity well, time will move at the same rate EXCEPT for the fact that the Earth is moving at a pretty good clip.

Traversing a gravity well should affect time, though. That's my best guess.

How to test it? Let's suppose you're on a planet that has Earth's mass and is not in orbit. It's zipping along in a straight line. I am 50,000 miles away in space, moving parallel to you at the same speed. Time would move at the same rate for us both.

Add a third guy who is actively falling into the Earth. Time would pass differently for him. He's traversing the well. I've heard that a person flying into a black hole would never reach it. Time would all but stop for him. The universe would end before he'd reach his target. It wouldn't much matter, though. The black hole's gravity would rip the poor fellow and his ship asunder long before his time slowed appreciably.

Decomposed > You have to be dealing with really big numbers before their shortcomings much matter.


And those 'Big Numbers' would be for things like trying to push ones rocket ship up to light speed . . . Or what happens if one tries to penetrate the event horizon of a black hole, right?

Or maybe even 'what happens inside the particle accelerator stays inside the particle accelerator' (I hope).

Am I right in thinking that scientific experiments have demonstrated that time passes at a slightly different rate outside the earths gravity well?

So much science . . . so much math . . .
